  Introduction Alumina (Al₂O₃) reinforced copper matrix composites have attracted significant attention in advanced materials research due to their unique combination of high electrical and thermal conductivity , good ductility , and excellent wear resistance . These properties make them highly suitable for demanding applications in the electronic industry , rail transit systems , and thermal management components . However, achieving strong interfacial bonding between ceramic reinforcements and the copper matrix remains a major challenge. The inherent non-wetting behavior of Al₂O₃ with copper and the mismatch in thermal expansion coefficients often lead to weak interfaces, which can degrade mechanical, thermal, and tribological performance. Addressing these interfacial issues is critical for unlocking the full potential of Al₂O₃/Cu composites. Interfacial Challenges in Al₂O₃/Cu Composites The performance limitations of Al₂O₃ reinforced copper composites are primarily rooted in...

Introduction Electromagnetic pumps have emerged as reliable solutions for transporting electrically conductive liquids without mechanical contact , making them highly suitable for industrial, medical, and scientific environments . By eliminating conventional moving parts, these pumps reduce wear, contamination, and maintenance requirements. The present research focuses on an electromagnetic diaphragm pump driven by the interaction between time-varying magnetic fields and a permanent neodymium magnet embedded in a flexible diaphragm. Special attention is given to thermal behavior , as temperature variations strongly influence electromagnetic efficiency, material properties, and overall pumping performance. Electromagnetic diaphragm pump working principle The pump operates through electromagnetic actuation, where alternating currents supplied to electromagnets generate oscillating magnetic fields. These fields interact with the embedded permanent magnet, producing periodic diaphragm...

Introduction The rapid expansion of embedded systems in IoT modules , smart sensors , and wearable devices has intensified the need for fast and accurate numerical computations on platforms with limited computational resources.

Introduction During shale gas drilling operations in Central China, the reliability of measurement while drilling (MWD) tools is critical for real-time logging and operational safety. The pressure-resistant cylinder , a core structural component of the MWD tool, is continuously exposed to high stress, corrosive drilling fluids, and abrasive particles. In this study, a severe failure characterized by extensive microcracking on the outer surface of a Cr20Ni11 (UNS 308) austenitic stainless-steel pressure-resistant cylinder is investigated. The failure significantly compromised tool integrity and data reliability, making it essential to identify the underlying corrosion and fracture mechanisms from a materials science and engineering perspective. Macroscopic and Physicochemical Characteristics of the Failed Cylinder Comprehensive macroscopic morphology analysis and physicochemical performance tests were conducted to evaluate whether the failed pressure-resistant cylinder met standard...
